duplex designer and builder who can help you to realize your duplex
project. The following information is relevant for all duplex
development.
DUPLEX BUILDER SYDNEY - FIRE RATING REQUIREMENT
Duplex
home usually consists of two attached dwellings separated with a party
wall, garages or other spaces. Duplex can be single storey or double
storey. The party wall between the two duplexes need to be built in
full height from footing to the underside of roof cladding and is
required to be fire rated. Because of fire rating requirement, the
party wall is usually built in brick or concrete block. If it is to be
built in timber construction, special double stud details with fire
rated material in between will need to be adopted. The party wall
should also be built to achieve required acoustic rating.

BUILDER SYDNEY - VERTICAL DUPLEX
Sometimes
duplex home is interpreted as two dwellings in the same building
enclosure but one on top of the other. In this case, the floor
separating the two duplexes needs to be fire rated and acoustically
rated. The staircase serving the upper duplex should be separated from
the lower duplex in its own fire rated enclosure or open.

BUILDER SYDNEY - SEPARATE SERVICES & METERING
When
building duplex homes, duplex builder should provide two separate sets
of water supply pipes, waste water pipes, underground drainage pipes,
electrical cables and gas pipes. Duplex builder also needs to install
separate connection and meters of the above services. Stormwater pipes
can be joined up before connection to the street gutter. However,
councils usually require stormwater detention system to be installed on
site before connection to street gutter.

BUILDER SYDNEY - MODIFYING EXISTING BUILDING
If an
existing house is to be modified to become a pair of duplexes, the

building services can be altered to accomodate fire rated party wall,
or fire rated floor, separate water supply, separate electrical
cabling, and separate gas service.
